Parameters Study on generation of uniform copper droplet by Pneumatic Drop-on-Demand Technology
Studying on the mechanism and device for high-melting-point metals droplets deposition technology are imperfect.In our research,a pneumatic driven droplet generator was developed to generate mono-sized copper droplets.Experiments were conducted to investigate the influence of spray pressure and pulse width on the size of droplets.Droplet was stably ejected while spray pressure was between 30kPa and 35kPa and pulse width was between 600μs and 900μs.The droplet size increased as the spray pressure increased.However the pulse width had no significant impact on the droplet size.At last a copper column was fabricated to certify the stability of the system and the reproducibility of the parameters.
